STEAM-ENGINE.

SPECIFICATION forming part'of Letters Iatent No. 397,468, dated February5, 1889.

Serial No. 272,177. (No model.)

To all whom it may concern:

Be it known that I, GEORGE \V. PRICE, a citizen of the United States,residing at Baltimore, in the State of llla-ryland, have inventedcertain new and useful Improvements in Steam-Engines, of which thefollowing is a specification. I

My invention relates to improvements in steam-engines, and isillustrated in the accompanying drawings, in which Figures 1 and 2 arevertical sections of the engine. Fig. 53 is a top view of the bottomcylindenhead. Fig. -l shows two views of the slide-block. Fig. 5 is ahorizontal section of the cylinder on line 5 The engine is of thevertical class. The letter A designates the cylinder; B, the stand whichsupports the cylinder, and (1 the crankshaft in bearings (Z in the baseof the stand. The piston E has a diametrical bolt, 6, to which one endof the rod F is pivoted, while the other end is connected with the crank0. As this one rod connects from the piston E directly to the crank C,it serves as both piston-rod and pitman. The top head, G, of thecylinder is oi ordinary ((HlStl'llCtlOll. The bottom head, G, has acentral slot, 71, and on its upper surface a dovetailed slideway, z'. Adovetailed slideblock, J, fits in said slideway and reciprocatescrosswise of the lower cylinder-head. The slide-block has a centralhole, 1:, and a concaved seat or bearing, Z, at each of two sides, whichis occupied by the T- shaped head in of a piston-rod sleeve, N. The

T-shaped head is cylindric and fits steam tight in the concaved seat Z,and is confined thereto by bands nt. The sleeve N extends downwardthrough the hole It" in slide-block J, and also through the slot 7! inthe bottom cylinder-head. The sleeve is pendent below the cylinder andswings or vibrates. The lower end of the sleeve is provided with apackingbox, 0. The pistons-ed F extends through the sleeve N andpacking-box.

It will be seen that as the piston E reciprocates the lateral motionimparted to the lower end of the rod F by the crank causes the block Jto slide back and forth on the lower cylinder-head, and the pendentsleeve N, which is carried by the block, is caused to vibrate.

The cylinder is provided with a stea1nchest, p, ports 6 e to thecylinder, an exhaustopening, 0', central between the said two ports, andan exhaust-port, 0, leading therefrom to the side. A disk-valve, q, ismounted on a shaft, (I, which passes through a stuffing-box, a, on thecover of the steamchest. The outer end of the shat'thas a crank, (Z'.The valve has an inlet-port, j, which opens through it, and as the valveoscillates this port is brought into coincidence with first one and thenthe other port, 6, leading to the cylinder. On its inner face the valvehas an exhaust-recess, As all these valve parts are fully shown anddescribed in my application for patent, Serial No. 258,414, filedlDecember 19, 18%, further explanation here unnecessary. The valve isoscillated by a lever, 7', which is attached to a pivot, The upper endof the lever is suitably attached to the valve-crank d, and the lowerend attached to a pivot-stud, t, on the piston-rod sleeve N. Theswinging movement of the sleeve will impart a vibrating movement to thelever 1', which, by acting on the valve-crank, will cause the valve q tooscillate.

Having described my invention, I claim 1. The combination, with the headof a steam-cylinder, through which the piston-rod works, of a dovetailedslide-block moving in a dovetailed slideway in said head, and the sleevehaving a Tshaped head resting in a concave seat in the block andprovided with a packing at the lower end, through which the piston-rodworks, the sleeve extending through a slot in the piston-head,substantially as specified.

2. A steam-engine having, in combination, the cylinder provided with apiston, and having at one end a slide-block, J, which reciprocatescrosswise of the cylinder-head, a diskvalve provided with a crank, d, asleeve, N, proj ecting from the slide-block, provided with a pivot-stud,1, and capable of vibrating, a main crank, C, a rod connecting thepiston and main crank and extending through the said sleeve, and alever, 1, having one end attached to the valve-crank, the other endattached to the said pivot-stml, and pivoted at s between its ends.

In testimony whereof I .affix my signature in the presence of twowitnesses.
